Browse aftermarket replacement parts for the Bobcat 543, the compact utility machine of Bobcat's classic 40-series era.
Use filters or search by OEM part number to find the right part. Compatibility details are listed on each product page.
The 543 filled the tight-access role in Bobcat's classic lineup, a machine small enough for doorways and barn alleys that still ran the family's proven layout. Its listings reference serial ranges of 502412001 and above and 511111001 and above, tracking its build phases, and the serial plate settles which applies to your machine.
Fitment on the 543 follows the small-frame classic pattern: chassis and control hardware overlaps the 540 and 542 heavily, while its diesel's service parts stay engine-specific. Product pages carry each part's full application list.
Routine service leads on this machine: the in-line fuel filter replacing OEM 3885315 and hose clamps like the size 5 replacing OEM 42H32 cover the fuel run, while the press fit bushing replacing OEM 6665701 and vibration damper replacing OEM 6560633 handle chassis wear. Rectangular washers replacing OEM 6553709 and hex hardware complete the small-frame rebuild kit.
Order by the OEM number from your parts manual where possible, and our team can confirm range coverage from your serial number.
